In Great 17 Claims.

This invention relates to garment-renewing machines of the type in whichthe fabric to be treated is placed .upon a support and is pressed uponby a rotary rubbing face to which may be supplied a fluid which .comesbetween said face and the fabric.

In machines of the type stated as hitherto used, the rubbing face ispresented by a single rotary device. The rotary device consists of aholder .in which is inserted an abrasive disc suitable for givingappropriate pile-raising or other renewal treatment to a garment. Thisdevice must be worked over the surface ofl the vfabric, including seams,with the result that the rate of progress is slow. l

The rotary device, which presents a rubbing face, is .embodied in aso-called pressure head. .In use of the machine a worker holds thepressure head by a control .handle and presses the rotary device uponthe work. The magnitude .of the pressure applied by the rotary device tothe .fabric is a vitally .important factor in the per.- iormance of thework, .so much so that the sense of feel in a worker must be developedby thor ough training before she can use one oi these machinessuccessfully.

An object of the present invention is to make provision in a-machine/ofthe type .stated whereby Ia reliable indication of the pressure beingexerted on the work is continuously presented to the worker so that she`is enabled to maintain the pressure at some predetermined `magnitudewithout relying l,upon her own sense of feel.

.Another object .of Vthe invention is to provide in a machine cf thetype stated a plurality ci rotary Afabric-renewing .devices which .areappli-` cable under pressure to vthe .fabric and which are spaced aroundthe axis oi apressure head'wherein they are incorporated, the `rotarydevices being respectively geared with a central drive.

, Another object is to provide in such a machine a pluralityy ofnormally co-planar rotary fabricrenewing devices applicablesimultaneouslyunder pressure to the fabric and in which the rotarydevices are 'individually movable against spring resistance in relationto one another to allow for formations such *for 'instance as seams Yon,or varying textures in, the fabric. The movements o which the devicesVare individually capa ble may comprise vertical and tilting movements.

The pressure head may have a handle lsc supported that by `manipulationof the handle the head and the assembly oi rotary devices thereinincorporated can be turned about the axis ci the Britain September 16,1.944

2 pressure head to suit the lie of the work on the garment support,

Another object of the invention is to provide r'in `such a machine anassembly of rotary devices mounted in the pressure head so as to bedisplaceable as an assembly in the headagainst a yielding springresistance when working pressure is applied to the pressure head.

Yet another object is to provide in such a machine locking means,preferably automatic, to holo; the one or'more rotary devices down totheir wor In a preferred form, the machine has one or more rotaryfabric-renewing devices arranged on a holder and adapted to be appliedto the work against spring pressure, such application involving relativemovement y,between said holder and devices anda pressure gauge on saidholder operatively connected lto the one or more devices and adaptedbythe relative movement to give an indication ofthe applied pressure.The machine also includes an overhead support, an extensible connectionbetween said overhead support and the holder on which the one or morerotary devices are arranged and a locking device serving to lock saidholder against return movement relatively to said support when saidconnection is extended by the application of working pressure to amagnitude indicated by the gauge.

A garment-renewing machine embodying the invention will now be describedby way of example with reference to the accompanying drawings in which:

Fig. 1 is an elevation ci the machine in out-ofuse position, portion-sof parts being broken away and shown in Vsection for clearness. Fig. 2is a section -on Ithe line V2"2 oi Fig. 1, being drawn to a largerscale. Fig. 3 is a plan of parts constituting the `top oi the machine.Fig. 4 is an elevation partly in section, of parts shown in Fig. 1, butlowered into their working position, thisy View lalso being drawn to alarger scale than Fig. 1. Fig. 5 4is a mid-section of parts of themachine as shown in Figs'l and 4, being drawn to a still larger scale,and Fig. 6 is a similar view of other parts. Fig. 7 isA a fragmentarysectional elevation of the component herein referred to as the pressurehead, the section being approximately on the line 1--1 of Fig. 9. Fig. 8is a sectional plan of the pressure head, the section being on 'the line8--8 of Fig. 1 and the view being drawn to a larger scale. Fig. 9 is afragmentary section approximately on the line 9-9 of Fig. *7, certain ofthe parts being broken away te show parts below them. Fig. 10 is aninverted plan of one of the rotary fabric-renewing devices fitted withan annular brush.

The means whereby the working components ofthe machine are supportedcomprise a base I, a vertical post 2 at one side of the base and ahorizontal jib 3, extending overhead acrossfthe 4base from the top ofthe post, a motor-carrying structure 4 from which a pressure head 5depends being carried by and immediately below the jib and a buckboard 6constituting the garment support being mounted on the post. The jib andthe buckboard are connected respectively at 'I and 8 to the post, andeither one of the connections may be a swivel whilst the other is rigidwith the post. Thus, provision is made for relative lateral movementbetween the pressure head and the work, which is denoted by 9, Fig. 4.

To ensure steadiness in use of the machine the' base has a three-pointsupport, namely threey runners or casters I9, one of which is locatednear the post at the rear of the base and the other two of which arenear the front corners thereof. The base has a cabinet II which can be.equipped as a garment-drying receptacle by fitting it with appropriateair heating means.

The pressure head includes an assembly of three rotary fabric-renewingdevices I2, although any desired plurality may be used. The devices (seeFig. 7) are connected to rigid vertical shafts I3 journalled in alocating plate I4 which consists chiefly of three radial arms. Theholder of the devices I2 and plate |4 is a casing I5. The plate I4 isvertically displaceable in the casing I5, being guided by arcuateflanges I6 at the ends of its arms sliding against faces I1 in thecasing. The flanges I6 have feathers I8 that are slidablegin slots ISAformed in the faced portions of the casing I5 to hold the plate I4 andthe rotary devices I2 against turning movement relatively to the casingI5 around the vertical axis of thecasing. That is to say, the devices I2are confined to rotation about their own axes. device-carrying shaft I3is polygonal in crosssection and has a gearwheel I9 connected to it,

, andthe three gearwheels I9 are arranged around a central gearwheel 29with which they mesh in the manner of planet-wheels with a sun-wheel.The central gearwheel is keyed to a rigid vertical -rotary shaft 2|forming a part of a telescopic driving shaft dependent from overhead.The device-carrying shafts I3 are capable 0f limited vertical movementrelatively to the plate |4 through the gearwheels I9, which arejournalled in ball-bearings 22, 23 on the plate I4 and are held againstvertical movement relative thereto by an abutment nut 24 on theelongated boss 25 of each of these gearwheels. Small strong springsEach,

and the associated abutment nuts 24 to oppose upward movement of therotary devices and their shafts I3 relatively to the plate |4. A setscrew 21 on each shaft I3 limits its downward movement, the arrangementbeing such that each groove connections 30 with one another (see Fig.-'1). 'The arrangement is such that each rotary device |2 is not onlycapable of being forced up- "rotary device I2, when pressed upon thework 9,

4 wards independently of the others but can adopt a position askew tothe axis of its shaft I3, for

example if necessitated by the contour of the raised portion of the work9, say a seam, that device will be forced to rise relatively to theothers and will tilt itself, by virtue of its universal joint 2li-30, inso far as may be necessitated by the lie of the work.

The previously mentioned telescopic driving shaft also includes a length3| the lower end of which is formed as a socket 32 which is slidablyconnected with the other shaft part 2|. The part 2| and socket 32 arepolygonal in cross section. The foot of the shaft part 2| is supportedby a foot-step ball-bearing 33 in the boss 34 of the plate I4 and theother shaft part 3| is journalled in a ball-bearing 35 in the casing I5.

A compression spring 36 is interposed between a collar 3IA on the shaft3| and the central gearwheel 2U, said spring functioning to urge theentire assembly of movable parts constituting the active components ofthe pressure head towards their lowermost position, in which they areshown in Figs. 1 and 7. This lowermost position is determined by thefeathers I8 engaging detachable stops IBB which close the otherwise openbottom of the slots |8A provided for the feathers in the casing I5.Thus, when the rotary devices I2 are brought into engagement with thework 9, sufhcient downward pressure on the casing I5 forces them,together with the gearwheels I9 and 29 driving them and the plate I4supporting them, as an assembly upward in relation to the casing I5, theextent of movement being proportional to the magnitude of the downwardpressure. In this relative movement, the shaft part 2| telescopes in thesocket 32, the spring 36 being compressed.

The casing I5 is suspended from the motorcarrying structure 4 by atelescopic tubular shaft assembly, comprising an outer tube 31 securedby a xture 38 to the base of the structure 4, an inner tube 39 securedto the handle 4B of the casing I5, an intermediate guide sleeve 4|interposed between upper and lower portions of the outer tube 31 and alocking case 42 secured to the vfoot of the outer tube and serving interalia as a guide for the inner tube. Relative turning between the tubes31 and 39 is prevented by a feather 43 and groove 44 in the tubes 39 and31 respectively, said feather and groove forming a connection whichpermits the tubes to telescope.

The pressure head 5 is supported by tension springs 45, which if desiredmay be enclosed in telescopic cases (not shown). The springs 45 areattached to lugs on the fixture 38 and to lugs on a collar 46 secured tothe inner tube 39. In Figs. V1 and 4, the spring 45 therein shown isbroken away to show parts behind it.

TheA telescopic tubular shaft assembly 31-4I vand the central drivingshaft 2|, 3|, 32 cons. freely .turna-ble angularly about its verticalaxis, is freely movable lengthwise. of the buckboard 6 and is. freelymovable relatively to the buckboard crosswise thereof. The free angularmovement is got by virtue of a swivel mounting at 4.1 between. .the topof the structure 4 and a trolley boss 48 -on the jib .3. (see Figs- 2and 3). The free lengthwise movement is got by virtue of the trolleyboss 43 having two upper pairs of wheels 49 and twol under pairs ofwheels 5l] all journalled on armsv 5| and riding upon rails 52 shown asledges formedin two side-by-side members constituting the jib 3. Thefree relative crosswise movement is got by virtue of the previouslymentioned pivotal mounting of the jib vor the vbuckboard on `the post 2.All of the movements'of the pressure head are got by application of theArequisite forces to the handle ,40 on 'the part of the operator. Inregard to the .anguiar movement, such is got by appropriate manipulationof lthe handle 43, for instance in order to align .the rotary devices I2with formations such as seams or ridges on the surface of the fabricconstituting the w-ork 9, That is to say, it might be desirable to workone device (or two devices) along a raised surface of the fabric beyonda longitudinal, transverse or inclined seam whilst working the other twodevices (or other one device) over the main surface alongside the seam,the differences in level being automaticall'y allowed for by appropriateyielding of the springs 26 individual to the devices.

'Ihearrangement is such that the pressure head with or without thegarment-,supporting buckboard can be moved about by the operator as thework progresses, in vorder to bring any portion of the work under theaction of the pressure head.

The drive to the rotary devices is imparted `to their central drivingshaft 3l by an electric motor 53 through intermeshing gearwheels 54, 55.-The Ymotor is supported by a bracket 56 on the carrying structure 4,being arranged with its axis vertical. Ihe gearwheel 55 is journalled inv`ball-bearings- 51 (see Figs. 2, 4 and 5) in a bracket 53 secured tothe structure 4. The shaft 3l has a sliding connection with thegearwheel 55, the uppermost portion of the shaft and the bore of thegearwheel being polygonal in cross-section. Thus, in Ythe falling andrising of` the shaft 3| with the pressure head 5 to and from thebuckboard E, the gearwheel 55 remains located in its bea-rings.

Each rotary device I2 comprises mainly a disc 59 made of rubber or otherabrasive material (see Fig. 1), the disc being clamped in place by aring holder 6.0. A brush 6l may be used in combination with each discwith Athe objects of cleaning and otherwise preparing the texture of thefabric 9 for treatment by the the fabric liquid supplied thereto throughthe disc, and raising and improving the nap of the fabric after suchtreatment. In the example, the holderf of each disc 59 annular collar 62(see also Fig. 10) which is faced with the brush material 6l, forinstance bristles or hair, and which is secured to the holder by meansof say a bayonet joint 63, or otherwise as may be convenient. Instead,the arrangement might be such that each disc is removable from itsholder and is replaceable by a circular brush of substantially the samesize as the disc. A machine having such brushes for use in place of theabrasive discs can be used for dry surface cleaning of garments.

dsc, removing from is adapted to receive an` 'The machine shown isequipped with an over head` reservoir 6.4 for lthe chemical liquid to besupplied to the pressure head for y.appligation through the rotarydevices I2 and rubber discs therein tothe .fabric preliminary to the.-usual treatment with the liquid. The reservoir 64 ,is mounted on themotor-carrying structure 4, which is made as a closed. housing for themotor 53. and associated gearing and for the reservoir. The lliquid isled through piping 6.5l to the handle 4B', which is provided in knownmanner with an internal self-closing valve (not shown) adapted 'to beopened by depression of' a nger lever 66 o n the handle. Piping 61 fromthe handle leads tobranches 68 (Figs. '1 and 8.) having three small`control/valves 69 from each of which extends a supply spout 1.3directed upon the inner wall 1..| oi an annular chamber 12 on theassociated ro.- tary device l2. The chamber 12 of each device opensthrough ports 13 to the active face vof the disc 59.

The motor-supporting structure 4 also encloses a switch connected inthev motor circuit and adapted automatically to start and stop the motor53 when the pressure head 5 is` lowered for and returned from work. Inthe example, the

automatic switch is of the lfluid type, comprising a tiltable tube '-14made of a suitable insulating thermo-setting plastic (such as thatmarketed under the trade-mark Bakelite'). The tube 14 is carried by aleverv 15. -tl'ig 2) fulcrumed on a bracket 15 secured toa wall ofthestructure .4. The lever is acted upon by a spring 11 that holds, orstrives to hold, the lever 15 against a stop 18, the tube 14 then beingin a position in which the `huid-namely, mercury or anelectrically-con.- ducting oil-makes contact between the switchterminals, which are connected in the motor circuit. The tube isarranged to co-operate with a striker 19 on top of the shaft 3|. Thearrange.- ment is such thatwhen the pressure head 5 is permitted by theworker to rise to the position according to Figs, 1 and 2, the str'ker1-9 uptilts the switch 14, 15 and the fluid breaks contact, thusstopping the motor. Conversely, when the pressure head 5 is loweredtowards the work, the striker 13 falls from the lever 15, and the springpulls the switch into the motor-starting position, so that by the timethe rotary devices l2' reach the work 9 they are rotating at full speed.

In the mach-ine shown, provision is made for holding the rotary devicesdown to their work against the upward pull of the springs 45 upon the`inner tube 39, so that the work will continue under the pressure of thespring 36, such pressure being proportional to the extent to which thespring 35 is compressed by the operator in forcing the pressure head 5upon the work (Fig. 4); The means'provided consist of an automaticone-way clutch (il)` housed in the previously mentioned locking case 42,which is secured to the outer tube 31 and embraces as a guide to theinner tube 39. The clutch B0 (Fig. 6) is of the known ring typesometimes referred to as a friction pawl, the ring being formed so as toencircle losely the inner tube 39 and its inner periphery being edged sothat the ring bites the inner tube 39 when the ring adopts the fullyinclined position in which it is shown. One side of the clutchvringrests at 8| upon the bottom of the locking case 42; and the ringcooperates with the stop 82 depending from the cover of the oase 42. Theclutch ring 8.0 automatically adopts the lockingv position in which itis shown because .of its tendency to. fulcrum about the stop 82 and bitehard upon the inner tube 39 under the urge thereof to rise under thepull of the springs 45, the arrangement being such that the ringeffectively prevents upward movement of the inner tube so long as thering adopts its fully inclined position.

The clutch ring is capable of locking the inner tube 39 only againstupward movement; that is to say if downward pressure is applied by theoperator to the pressure head 5, when raised, the clutch ring cannothinder downward movement of the pressure head, the inner tube 39 slidingdownwards freely through the ring.

A nger piece 83 is arranged diametrically opposite to the stop 32,projecting freely through the bottom of the case 42 and engaging thering 89. In the even that the pressure head 5 is lowered and the innertube 39 is locked by the ring Ell against rising, the operator can pulldown the ring B by means of the finger piece 83 into a non-lockingposition, in consequence of which the springs 45 pull the pressure headupwards into the out-of-use position.

A spring 84 may be provided to expedite and render surer the automaticaction of the ring when adopting and maintaining its locking position.It is convenient to arrange the stem of the iinger piece 83 through thespring 84, if a spring is provided.

In the machine shown, a pressure gauge 85 is provided on the casing I ofthe pressure head in order to indicate to the worker the magnitude ofthe pressure being applied to the fabric 9 by the rotary fabric-renewingdevices I2 collectively. As shown in Fig. '7, the plate I4, which risesand falls as part of the assembly of working parts within the casing I5,is connected at 8B to a rod 8'! the top of which is formed at 88 as arack, which forms a component of the pressure-gauge mechanism. Thismechanism also includes a pointer 89 (Fig. 8) co-operating with agraduated scale 99 marked with any appropriate values or units, such forinstance as lbs. per square inch, indicative of the total pressureapplied by the rotary devices. The pointer is connected in known mannerthrough appropriate gearing (not shown) within the gauge 85'to the rack38.

The buckboard 6 consists of a single ironing board or the like. Theboard may form one of a number of such boards, respectively made fordifferent classes of work. These boards are made so that any selectedone of them may be rigidly attached to the connection 8 provided forthem on the post 2 of the machine. Any appropriate means of attachmentmay be provided. For example, as indicated by Fig. 1, the board 6 mayhave secured to its underside a channel 9| which is adapted to slidefirmly uponoa T-section arm 92 extending horizontally from theconnection 3. A device 93, such as a set-screw or a spring catch, may beprovided on the channel 9| for locking thereof to the arm 92 in theproper po sitional relationship of the board 6 to the connection 8.

The garment renewing machine is operated in the following manner:

When the machine is not in use, the pressure head 5 adopts its raisedposition, in which it is suitable to the'work is secured to theconnection 8. Thereafter, a fabric 9 constituting the work :isappropriately placed upon the buckboard. The operator grasps the handle4B and presses down the pressure head 5, against the pull of the springs45, towards the work, depressing the lever 66 in the usual manner as thework is reached in order to start the ow of liquid by way of the valves69, which are open to a previously regulated extent. As the operatorlowers the pressure head, the inner tube 39 slides freely through theclutch ring 8D; moreover the striker 'I9 is retracted from below thelever '15, with the result that the switch 'I4 is tilted to close themotor circuit and thus start the motor 53. Accordingly, by the time thatthe rotary devices I2 reach the work (Fig. 4), the devices are rotatingat full speed and liquid is being supplied to the work through the ports13. The operator continues the downward pressure in order that therotary devices will exercise the desired working pressure upon thefabric. Accordingly the spring 36 is forced to yield by the assembly ofworking components within the casing I5. Meantime, the operator watchesthe pointer 89 of the gauge 8'5. When the pointer reaches a marksuitable for the working pressure to be exercised upon the work in hand,the operator ceases to press downwards upon the handle 40, with theresult that the automatic clutch ring bites into the inner tube 39 andlocks the entire suspensory apparatus against withdrawal from the work.l The upper reaction against the suspensory apparatus by the work istaken by the lower trolley wheels against the rails of the jib 3. Theoperator now moves the pressure head 5 over the work, turning thepressure head if desired about its vertical axis by swivelling at 48, ormoving the pressure head laterally by movement of the trolley along thejlb 3, or effecting relative crosswise motion between the pressure headand the buckboard 6 about the axis of the post 2.

In the foregoing description of the operation of the machine, the threerotary devices I2 are considered as an assembly. In the event that oneor more of these devices encounter formations on the fabric differentfrom the general plane of the work, such device or devices willautomatically adjust itself or themselves by virtue of the springs 26and universal joints `28, as hereinbefore explained.

In the event that one or more of the rotary devices are beinginadequately or excessively supplied Iwith liquid, appropriateadjustment is made to vthe associated valves B9.

When the Work in hand is completed, the operator pulls down the fingerpiece 83, thus unlocking the clutch ring 89 with the result that thesprings 45 lift the pressure head 5 into the outof-use position. Asusual the operator releases the finger lever 66, so that the supply ofliquid is shut off. As the out-of-use position is approached, thestriker 'I9 returns the switch 14 to its raised position, in which themotor circuit is opened Iand the motor stopped.

The machine hereinbefore described with reference to the drawings is anexample embodying the invention and is subject to modifications. Forexample, in a machine not having a locking device, such as the automaticone-way clutch 80, and not having la pressure gauge to indicate theworking pressure, the drive from the overhead motor to the pressure headneed not consist of rigid members such as the driving shaft 2I, 3|

and the tubular supporting means 3l, 3e but may consist of aV flexiblecable drive such as is already known in machines of the. type tol whichthis invention relates.
